Abstract The quartz tube solid particle air receiver is a new type of solar receiver in which fluidized particles absorb the solar radiation directly and heat the air effectively, improving the efficiency of solar thermal power generation and reducing costs. In this article, transient numerical simulation was conducted to simulate the heat transfer and flow processes in single quartz tube under concentrated solar radiation. The results showed that the distribution of solid particles temperature was uniform in the fluidized region, which could overcome the problem of overheating in the volumetric solar receiver. The temperature difference between solid particles and air was no more than 25K, indicating that heat transfer between particles and air was very effective. Further, as the direct solar radiation increased, the average air temperature in the outlet increased while the thermal efficiency decreased. The high tube wall temperature caused heat loss to the environment by radiative and convective heat transfer. With the air inlet velocity increasing, the averaging air temperature in the outlet decreased while the efficiency of the receiver increased. The simulation results provided important reference for improving the performance of the quartz tube solid particle air receiver The Authors. Published by Elsevier Ltd.

2 574 F. Wang et al. / Energy Procedia 69 ( 2015 ) should be implemented [1]. Solar particle air receiver in which solid particles absorb the solar radiation and transfer the heat to the flowing air is a promising candidate. Hsieh HT et al. [2] simulated particlegas flow within a solid particle receiver and analyzed the factors that could affect the performance of receiver. Nathan P. Siegel et al. [3] developed and evaluated a prototype solid particle receiver. According to their experiment, particles can be heated to more than 900 o C, which demonstrated that such receiver can be used in practice. However, the above researches mainly focus on falling curtain particle receiver in which the solid particle volume fraction is no more than 3%. In 2013, F. Bai et al. [4] developed and tested a five quartz tubes solid particle air receiver on a solar furnace system with more than 20 % solid particle volume fraction. The approximate solid particle size was 3mm. In this paper, the solid particle air receiver with single quartz tube was simulated numerically by CFD (Computational Fluid Dynamics) software Ansys Fluent The results displayed the heat transfer mechanism between solid particles and air in the solar receiver and provided important reference for improving the performance of such air receiver.

(a) The receiver prototype; (b) The structure of receiver Before starting up, the solid particles stack at the bottom of the quartz tube. During the operation, the ambient air is blown into tube by the fan or air compressor to make the particles fluidized. The fluidized particles are exposed to the concentrated solar radiation that passes through the quartz wall. The solar energy is absorbed by the dark particles and transferred to the flowing air. Then the hot air comes out from the top of the quartz tube. In this article, the CFD software is utilized to simulate the operation of single quartz tube solid particle air receiver, including the gassolid flow and heat transfer between them. The single quartz tube used in the numerical simulation is 0.5m in length, 0.04m in outer diameter and 0.003m in wall thickness.
4 576 F. Wang et al. / Energy Procedia 69 ( 2015 ) Governing equations A three dimensional CFD numerical simulation was performed to simulate the quartz tube solid particle air receiver. According to the volume fraction of solid particles in the receiver, Eulerian Model was selected in the numerical simulation. The equations of continuity, momentum and energy of both air and solid particles are listed as follows [5]. Equations of air: Continuity equation: i [(1 zp) f ] [(1 zp) fuf ] 0 i t x (1) Momentum equation: i i ij uf uf pf f (1 z ) (1 z ) u F F j i j t x x x j i i p f p f f bf fp (2) Energy equation: 1 1 [(1 z ) ( e u u )] [(1 z ) u ( e u u ) F Q ] E F u j t 2 x 2 i i j i i j j j j p f f f f p f f f f f sf cf fp bf f (3) Equations of solid particles: Continuity equation: i [ zpp] [ zppup] 0 i t x (4) Momentum equation: u u p z z u F F t x x x i i ij p j p p p i i pp pp p j i j bp pf (5) Energy equation: 1 1 [ z ( e u u )] [ z u ( e u u ) F Q ] E F u j t 2 x 2 i i j i i j j j j p p p p p p p p p p p sp cp pf bp p (6) As for the dense gassolid turbulent flow in the simulation, standard kepsilon model was more suitable to conduct the simulation.

5 F. Wang et al. / Energy Procedia 69 ( 2015 ) The solid particles played an important role in absorbing and scattering the concentrated solar radiation in the quartz tube solid particle air receiver while the air was considered to be a nonabsorbing media. Thus, the P1 radiation model that ignores the air radiation is presented as the following equations [78].

Gunn model is frequently used for Eulerian multiphase simulations, especially for dense gassolid simulation. In order to simulate the heat transfer between solid particles and the air, Gunn model was utilized in the simulation. The equations of Gunn model are as follows [9].

Numerical procedure f p p f f p f f f The numerical simulation involves complex multiphase flow and convective and radiative heat transfer. Therefore, the main assumptions are given as the following. (1) The air is incompressible and Newtonian fluid, the air density varies with temperature. (2) The solid phase consists of spherical particles with uniform diameter and cannot react with oxygen. (3) The concentrated solar radiation is uniform and the incident direction is normal to the quartz tube wall. (4) The absorption coefficient of solid particles is independent with the wavelength of incident radiation. (5) The thermal conductivity in the tube wall is neglected. The numerical models used in the simulation have been mentioned above and incident radiation is simulated by Solar Ray Tracing model in Ansys Fluent. The quartz tube geometry is meshed by hexahedron with the grid number of Two cases with different direct solar radiation are simulated. Further, the initial parameters in the numerical simulations are listed in Table 1.

The initial parameters in the numerical simulations Parameter Direct solar radiation1 (kw/m 2 ) Direct solar radiation2(kw/m 2 ) Solid particle name Diameter of solid particle (mm) Inlet air velocity(m/s) Inlet air temperature(k) Packed height of particles (mm) Glass transmissivity of visible Glass transmissivity of infrared Ambient temperature(k) Convective coefficient on outer wall (W/(m 2. K)) External emissivity Time step size(s) Gravitational Acceleration(m/s 2 ) Value SiC The size of solid particles in the receiver is much larger and thus the velocity should be higher in order to make the solid particles fluidized. The solid particles may be blown out of the tube, so the initial particles packed height is much lower than the tube length. The fluidized particles concentrate in the lower part of the tube and volume fraction of solid particles in this region is more than 20%. Because of the complexities of dense gassolid turbulent flow, convective and radiative heat transfer processes in the tube, the time step size is set to 0.001s and the residual of continuity, velocity and energy are According to the parameters mentioned in Table.1, the numerical simulation lasted for more than 5 minutes. The temperature of solid and air became steady after being simulated for 5 minutes. Results and discussions are listed as follows. 3. Results and discussions 3.1. Distribution and analysis of temperature Fig. 2(a) shows that the direct solar radiation injects into the receiver from positive Yaxis. The direct solar radiation distributed on the positive Yaxis tube wall was much higher than that on other walls. The phase distribution of solid particles in the receiver after being simulated for 5 minutes is as shown in Fig. 2(b). Most fluidized particles concentrated in the lower part of the tube. The Zcoordinate of the highest solid phase plane was less than 0.15m. Thus, most of the heat was transferred from solid particles to air in the lower part of the tube.

(a)the distribution of solar radiation on the tube wall (b) The distribution of solid particles in the tube Fig. 3 and Fig. 4 show distributions of air and solid particles temperature in the tube under different direct solar radiation conditions. The distributions of air and solid particles temperature were uniform in the lower region of the tube. Most fluidized solid particles concentrated in the lower region of the tube and the air and solid exchanged heat effectively in this region. The temperature of air and solid in Fig. 4 were much higher than that shown in Fig. 3, which was due to higher direct solar radiation. In the upper region of the tube, there was almost no solid particle and the temperature of air distributed less uniformly. The air temperature closing to the tube wall was higher than that in the center of receiver because of the higher tube wall temperature partly. As for the rise of the air temperature in the upper region of tube, more research needs to be done in the future. Further, the air temperature distributed comparatively less uniformly along the Yaxis than that distributed along Xaxis as the concentrate solar radiation injected into the receiver from positive Yaxis. a b Fig. 3.

Analysis of thermal performance In order to get higher outlet air temperature, it is necessary to enhance heat transfer efficiency between solid particles and air. As Fig. 5 showed, the average temperature difference between solid particles and air was less than 25K in both two cases, which indicated that the heat transfer between solid particles and air was very effective. As simulating time went by, the temperature difference between two phases became steady. Compared with direct solar radiation of 1200 kw/m 2, the lower the direct solar radiation resulted in the less temperature difference between two phases. Fig. 5. The volumetric average temperature difference between two phases The transient thermal efficiency of the quartz tube solid particle air receiver is defined as given. Q Q air (16) total Fig. 6 showed the detailed analysis of thermal performance in single tube solid particle air receiver, including average outlet air temperature and transient thermal efficiency of receiver. In the condition of direct solar radiation 600kW/m 2, the average outlet air temperature was more than 800K and the thermal efficiency was about 76.7% after being simulated for 5 minutes. The average outlet air temperature was close to 1100K in the condition of direct solar
9 F. Wang et al. / Energy Procedia 69 ( 2015 ) radiation 1200kW/m 2 but thermal efficiency decreased to 64.4%. When the direct solar radiation increased, the outlet average air temperature increased while the thermal efficiency decreased. Moreover, the tube wall temperature became higher in the condition of direct solar radiation 1200 kw/m 2, which caused more heat loss to environment through radiative and convective heat transfer. The total proportions of radiative and convective heat losses to the environment were 13.3% in condition of direct solar radiation 600kW/m 2 and 25.6% in the condition of direct solar radiation 1200kW/m 2. About 10% of direct solar radiation was reflected by the tube wall. In order to improve the thermal efficiency of the receiver, it is crucial to reduce the heat loss to the environment. In addition, the maximum tube wall temperature in these cases is K, which is lower than temperature limit of quartz glass. The analysis of thermal performance provided important reference for making improvements about the receiver later Analysis of various velocity conditions Fig. 6. The detailed analysis of efficiency in the receiver Fig. 7 shows detailed thermal analysis of various inlet air velocity conditions. The direct solar radiation applied in these simulations was 600kW/m 2. As the velocity increased, the average outlet air temperature decreased while the transient thermal efficiency of receiver in the fluidized region increased. The higher velocity contributed to the more effective heat transfer between solid particles and air. Thus, the temperature of solid particles could not rise to a high level, which caused that the average air temperature became lower. However, the air mass flow rate in higher velocity condition became larger and thus the air could transfer more heat with solid particles in the same time period, improving the efficiency of the receiver in the fluidized region. Moreover, it is significant to set up a proper inlet air velocity so that the particles can be fluidized steadily. Thereby, the outlet air temperature and transientthermal efficiency of the receiver can change smoothly, which is beneficial for the operation of the entire solar power plant.

Conclusions According to the numerical simulation of single quartz tube solid particle air receiver, the following conclusions are obtained. (1) The temperature of both solid particles and air distribute uniformly in the region where fluidized particles concentrate. For the upper region of tube where fluidized particles become dilute, the air temperature closing to the tube wall is higher than that in the center of receiver. (2) The temperature difference between air and solid particles is less than 25K, indicating the heat transfer between solid particles and air is very effective. (3) With the increase of direct solar thermal radiation, the average air temperature in the outlet increases while the transient thermal efficiency decreases. It is important to reduce the radiative and convective heat loss to the environment caused by high tube wall temperature. (4) With the increasing air inlet velocity, the averaging air temperature in the outlet decreases while the transient thermal efficiency of the receiver in the fluidized region increases. The air inlet velocity is important to ensure that the receiver can be operated in a steady way.
